在页面上防止非法字符输入Page_error
使用这样不会将错误抛给用户
//防止非法字符
protected void Page_Error(object sender, EventArgs e)
{
Exception ex = Server.GetLastError();
if (HttpContext.Current.Server.GetLastError() is HttpRequestValidationException)
{
HttpContext.Current.Response.Write("请输入合法的字符串【<a href=\"javascript:history.back(0);\">返回</a>】");
HttpContext.Current.Server.ClearError();
}
}
